Crowdsourcing ? “ I find the term incredibly irritating... Any company that thinks it’s going to build a site by outsourcing all the work to its users not only disrespects the users but completely misunderstands what it should be doing. Your  job is to provide a structure for your users to Collaborate, and that takes a lot of work”.  Jimmy Wales, Wikipedia
